I just did one on mine. You'll need one from a 240 obviously. It requires pulling the oil pump drive under pcv breather box. Also the distributor has a hard time going in on a block that never had one. I cleaned it up with some emery cloth and it went in. Set all your timing gears to TDC like when your putting on the timing belt and point the distributor just after where the #1 post on the cap would be. When you slide it in it will turn counter clockwise on the bevel gear to #1.

Make sure you use a gasket on the cover that holds the shaft in. Rtv won't work as the gasket gives the shaft thrust bearing enough clearance.

RTV shouldn't be allowed anywhere near a Volvo motor. I've spent at least a couple hours so far scraping and peeling RTV out of various parts of my B230FT. Last week I found it slathered all over and inside the fittings to the oil cooler thermostat housing so the hose was about 80% clogged up, best part is it wasn't even the fittings that were leaking.

I use some stuff called Hylomar Blue, and use it very sparingly in a few specific places. Most people use way too much sealant and use it in places that don't need or want it. There *are* a few places on these motors that need sealant, but only a few.
